A method for transmitting information, comprising:

• detecting a first unlicensed channel resource of a plurality of unlicensed channel resources that is in an unavailable state, the first unlicensed channel resource being configured for transmitting control signaling, and the plurality of unlicensed channel resources being configured by a base station;
• determining a second unlicensed channel resource from the plurality of unlicensed channel resources that is reserved for transmitting the control signaling according to a set rule;
• and
• receiving the control signaling via the second unlicensed channel resource.

An apparatus for transmitting information, comprising:

• a processor;
• and
• a memory configured to store instructions executable by the processor;
• wherein the processor is configured to:
• detect a first unlicensed channel resource of a plurality of unlicensed channel resources as being in an unavailable state, the first unlicensed channel resource being configured for transmitting control signaling, and the plurality of unlicensed channel resources being configured for a terminal;
• determine a second unlicensed channel resource from the plurality of unlicensed channel resources according to a set rule, the second unlicensed channel resource being reserved for transmitting the control signaling;
• and
• transmit the control signaling to the terminal via the second unlicensed channel resource.
